Abstract
The present disclosure provides for consistent reads in a global database that is replicated to one or more global clones. A state machine is implemented, and executed independently, for each project in each region. Based on the state of a project when a read request is received, the read request will be served by the global database, served by the global clone, or ignored as an invalid request.
